Designed for use in utter darkness, without any visible light source, night vision borescopes are a form of videoscope or industrial endoscope. There are two main varieties of these borescopes:

• Thermal Borescopes: Use thermal infrared imaging sensors to detect heat signatures.
• Infrared Night Vision Borescopes: Utilize invisible infrared light illumination for enhanced visibility in dark environments.

An infrared (infrared) borescope is an instrument for clearly viewing objects invisible to the human eye at night. Its infrared technology makes it perfect for low-light or overnight investigations.

By detecting the heat radiated by objects, thermal imaging cameras produce a thermal map of the investigated area. Finding problems such overheating, inadequate insulation, and air leakage is made easier with these cameras. Security staff also extensively rely on them for night patrols.

• Infrared Cameras: Detect near-infrared light.
• Thermal Cameras: Detect differences in radiation emitted by objects.

An IR borescope is another instrument for investigation combining efficiency, stealth, and adaptability. With infrared night vision and accurate examination in limited, difficult-to-reach locations, it can record vital information in low-light or dark conditions. Law enforcement makes extensive use of IR flexible borescopes, which are therefore rather helpful instruments for police officers on operations.
